(pbuh))

Bukhari :: Book 6 :: Volume 60 :: Hadith 410

Narrated 'Umar:

I recommend that my successor should take care of and secure the
rights of the early emigrants; and I also advise my successor to be
kind to the Ansar who had homes (in Medina) and had adopted the
Faith, before the Prophet migrated to them, and to accept the good
from their good ones and excuse their wrong doers.
